Product material overview
PE (high-density polyethylene) environmentally-friendly healthy drinking water pipeline adopts imported PE100 raw material and is manufactured according to GB/T13663 standard. The product has good weldability and environmental stress crack resistance, and its performance meets international and national standards.
The use of PE pipes, PE pipes are mainly used for the transportation of solid water or mixed materials such as water supply and drainage pipes, mining pipelines, sewage of chemical and pharmaceutical industries, and sand and mortar. The resistance inside the pipe is 25% smaller than that of metal pipes, which can greatly improve the transportation efficiency.
PE has a rich source of raw materials. From the molecular structure (C2H4), the molecular structure of PE is a simple type of polymer. PE pipelines are developing, constantly overcoming their own shortcomings, PE pipe connection, PE pipe heating and welding, requirements A certain operating space and skilled operating techniques. Later, an electric welded bushing was invented, that is, two pipe sections or pipe fittings were connected by an electric heat welding sleeve, which was used for the connection of the PE pipe in the pipe trench or where the construction space was small. The material properties of PE pipes are also improving. From PE63, PE80 to PE100, PE115 will be developed in the future. PE100 means that at 200 ° C, this grade of PE material can maintain a low strength (MRS) of 10 MPa after 50 years. PE80 is 8.0Mpa. With the improvement of PE material grade, the wall thickness of PE15 is lower than that of PE100, and the wall thickness of PE pipe is thinner, which reduces the amount of PE material. The cost is reduced, which is beneficial to the application of PE pipes in large diameter pipes.
The connection of the PE pipe needs to be heated, and a certain cooling time is required. It takes about 20 minutes for each welding. The longer the pipe diameter, the longer the heating and cooling time, so the installation period of the PE pipe is relatively extended.
Features
